Why do you act different? Because your partner is probably stressing you out! I love my lady, but man, sometimes I want space, inside, in my home, for a few hours; not just a few minutes. Silence and complete control over your environment can be empowering and liberating. Constantly sharing space, attention, and thoughts -- let alone household responsibilities -- can make you anxious, claustrophobic, and eager to escape.

I mean, when my home is constantly occupied, how am I going to whip out my dong and have a nice, slow jerk? Or skip doing the dishes for that matter without incurring the wrath of Miss Choremaster McBusybody? It's just not the same.

For most of history, nobody could be "alone and productive." This sort of alienation is only possible in species that have developed along a certain, shall we say, autistic, axis.

I go through a similar experience when my partner is away. I especially eat better and exercise more. But if you are actually considering ending a relationship because of this then you must not care about them that much. My partner and I are glued to the hip. Which can be a problem at times. But easily remedied. It's called communication and also you are part to blame for how you act when they are around. If I just work on it and talk to my partner they would understand no problem! I am very much responsible for how I act when my partner is around.

You aren't really concerning yourself with putting energy in to improving the relationship or figuring out why you aren't bothered to be your best self while your partner is around. I think that you should break up with your partner so that you can spend time enjoying your own company unfettered by any ties to another humans life. This way your partner can get on with being hurt by the disregard you have for them and the connection they thought you shared, with as much time as possible to find a partner that will want to be with them and work to improve the life they share.

Honestly I would compare a good partner that has left for a short while on a business trip to a short vacation. It's not your regular life, it's a little break, where you get some things done. I can tell you from personal experience, that if you break up, it's like moving country. You are alone a lot of the time, and while productivity is certainly enjoyable, you eventually burn out, and then you are all alone watching TV and eating too much. Plus, having sex alone for a long period, is shall we say, less than exciting. Especially for someone with a high sex drive.

Perhaps your partner and you are mismatched, perhaps not. Why not try involving them in your activities, instead of blaming them as the reason why you do not complete as many projects as you'd like.
If that fails, try being alone. If that fails, try finding someone as motivated to stay busy as much as you do.

It sounds like you're blaming the confessor for their problems. You have no idea what they or their partner is like.

maybe you shouldn't live together? It's stimatized but it shouldn't be. It sounds like you love your partner you just don't love living with them

I honestly have been thinking my next relationship I may not want to live with them-see how it goes
